Overview

The Washington Street Master Lift Station has been the principal wastewater pumping facility in the City of Bismarck since it was constructed in the 1950s. Approximately 60 percent of the wastewater volume generated in the city passes through this station. Because this lift station is such a vital component of Bismarck's sanitary infrastructure, assessing its condition and making recommendations for improvements were critically important matters for city staff.

The City of Bismarck selected and retained the services of Apex Engineering Group to provide planning, design and construction administration services for an upgrade of the Washington Street Master Lift Station, because of our teams' vast experience in pump station planning, design and construction services.

Approach

Apex worked with the City to:

  • Accommodate future flows of 11.4 mgd that includes the existing lift station service area and a future service area in Northwest Bismarck 
  • Replace and upgrade pumps, valves, fittings, and controls that provide reliable pumping capabilities for a 30-year service life 
  • Improve pump station reliability by designing redundant components 
  • Improve operational efficiency and safety 
  • Improve the aesthetics of the pump station, control the release of odors, and reduce equipment noise
Outcome

Bids were awarded in September of 2011; startup, testing and commissioning of the new pump station occurred in the fall/winter of 2012.
